The colon is one of the most important organs in your body and its job is to help your body remove waste.

Americans usually feel tired because of __________.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → lack of sleep
The passage opens by asking whether the reader always feels tired and then says that over 40 million Americans experience sleep deprivation on a regular basis. Sleep deprivation is not getting enough sleep, so the tiredness comes from a lack of sleep.
Why the Other Options are Incorrect?
Option 1: too much work — Incorrect. Not mentioned: the passage says nothing about long working hours as a cause of tiredness.
Option 3: poor diet — Incorrect. Wrong part of the passage: processed food and caffeine come up later, in the discussion of a detox; the tiredness of Americans is linked directly to sleep deprivation.
Option 4: detoxification — Incorrect. Wrong link: detoxification, the removal of harmful substances from the body, is offered as the remedy that gives "an energy boost", not as the cause of tiredness.
